ThinkPHP3.1迁移到PHP7

一、在PHP7中,preg_replace不能用/e修饰符,所以用preg_replace_callback代替preg_replace,
需要修改的文件包括

ThinkPHP\Lib\Template\ThinkTemplate.class.php
ThinkPHP\Lib\Core\Dispatcher.class.php
ThinkPHP\Lib\Core\Db.class.php
ThinkPHP\Lib\Behavior\CheckRouteBehavior.class.php
ThinkPHP\Extend\Mode\Lite\Dispatcher.class.php
ThinkPHP\Lib\Behavior\ReadHtmlCacheBehavior.class.php
ThinkPHP\Common\common.php

1)ThinkPHP\Lib\Template\ThinkTemplate.class.php

return $this->restoreLiteral($r[1]);
}, $tmplContent);

NO2. 大约在168行,将

return $this->parseLiteral($r[1]);
}, $content);

NO3. 大约在197行,将
[php] view plain copy

$content = preg_replace(‘/(‘.$this->config['tmpl_begin'].’)([^\d\s'.$this->config['tmpl_begin'].$this->config['tmpl_end'].’].+?)(‘.$this->config['tmpl_end'].’)/eis’,"\$this->parseTag(‘\\2′)",$content);
替换为
[php] view plain copy

$content = preg_replace_callback(‘/(‘ . $this->config['tmpl_begin'] . ‘)([^\d\s' . $this->config['tmpl_begin'] . $this->config['tmpl_end'] . ‘].+?)(‘ . $this->config['tmpl_end'] . ‘)/is’, function($r) {

}, $content);

[php] view plain copy

if (!$closeTag){
$patterns = ‘/’.$begin.$parseTag.$n1.’\/(\s*?)’.$end.’/is’;
$replacement = "\$this->parseXmlTag(‘$tagLib’,'$tag’,'$1′,”)";
$content = preg_replace_callback($patterns, function($r) use($tagLib, $tag) {
return $this->parseXmlTag($tagLib, $tag, $r[1], ”);
},$content);
}else{
$patterns = ‘/’.$begin.$parseTag.$n1.$end.’(.*?)’.$begin.’\/’.$parseTag.’(\s*?)’.$end.’/is’;
$replacement = "\$this->parseXmlTag(‘$tagLib’,'$tag’,'$1′,’$2′)";
for($i=0;$i<$level;$i++)
$content = preg_replace_callback($patterns, function($r) use($tagLib, $tag) {
return $this->parseXmlTag($tagLib, $tag, $r[1], $r[2]);
},$content);
}

2)ThinkPHP\Lib\Core\Dispatcher.class.php

5)ThinkPHP\Extend\Mode\Lite\Dispatcher.class.php

preg_replace_callback(‘@(\w+)’.$depr.’([^'.$depr.'\/]+)@’,function($r) use (&$var){
$var[$r['1']] = $r[2];
},implode($depr,$paths));
6)ThinkPHP\Lib\Behavior\ReadHtmlCacheBehavior.class.php
大约65行处的一个if判断替换为:

[php] view plain copy

if(!empty($html)) {
// 解读静态规则
$rule = $html[0];
// 以$_开头的系统变量
//$rule = preg_replace(‘/{\$(_\w+)\.(\w+)\|(\w+)}/e’,"\\3(\$\\1['\\2'])",$rule);
$rule = preg_replace_callback(‘/{\$(_\w+)\.(\w+)\|(\w+)}/’,function($r){
$system = "$r[3](\${$r[1]}['$r[2]‘])";
eval( "\$system = $system ;" );
return $system;
},$rule);
//$rule = preg_replace(‘/{\$(_\w+)\.(\w+)}/e’,"\$\\1['\\2']",$rule);
$rule = preg_replace_callback(‘/{\$(_\w+)\.(\w+)}/’,function($r){
$system = "\${$r[1]}['$r[2]‘]";
eval( "\$system = $system ;" );
return $system;
},$rule);
// {ID|FUN} GET变量的简写
//$rule = preg_replace(‘/{(\w+)\|(\w+)}/e’,"\\2(\$_GET['\\1'])",$rule);
$rule = preg_replace_callback(‘/{(\w+)\|(\w+)}/’,function($r){
return $r[2]($_GET[$r[1]]);
},$rule);
//$rule = preg_replace(‘/{(\w+)}/e’,"\$_GET['\\1']",$rule);
$rule = preg_replace_callback(‘/{(\w+)}/’,function($r){
return $_GET[$r[1]];
},$rule);
// 特殊系统变量
$rule = str_ireplace(
array(‘{:app}’,'{:module}’,'{:action}’,'{:group}’),
array(APP_NAME,MODULE_NAME,ACTION_NAME,defined(‘GROUP_NAME’)?GROUP_NAME:”),
$rule);
// {|FUN} 单独使用函数
//$rule = preg_replace(‘/{\|(\w+)}/e’,"\\1()",$rule);
$rule = preg_replace_callback(‘/{\|(\w+)}/’,function($r){
return $r[1]();
},$rule);
if(!empty($html[2])) $rule = $html[2]($rule); // 应用附加函数
$cacheTime = isset($html[1])?$html[1]:C(‘HTML_CACHE_TIME’); // 缓存有效期
// 当前缓存文件
define(‘HTML_FILE_NAME’,HTML_PATH . $rule.C(‘HTML_FILE_SUFFIX’));
return $cacheTime;
}
7)ThinkPHP\Common\common.php

大约217行,将
return ucfirst(preg_replace("/_([a-zA-Z])/e", "strtoupper(‘\\1′)", $name));

改为
$str = preg_replace_callback(‘/_([a-zA-Z])/’, function($r) {
return strtoupper($r[1]);
}, $name);

return ucfirst($str);

 

二、如果有用到验证码,请把ThinkPHP\Extend\Library\ORG\Util目录下的String.class.php复制一份放在一起,并改名为Stringnew.class.php

打开Stringnew.class.php
把所有的String::替换为Stringnew::

并把类名Class String 改为 Class Stringnew
打开ThinkPHP\Extend\Library\ORG\Util\Image.class.php,把所有的

[php] view plain copy

import(‘ORG.Util.String’);
替换成

[php] view plain copy

import(‘ORG.Util.Stringnew’);
三、自定义函数的参数最好给定默认值,如果自定义函数规定了参数,但是没有指定默认值,在外部调用的时候,如果传参的时候少传值了,那么运行会报错!

 

这样,在PHP7下就能运行ThinkPHP3.1了。
